Renewable energies has shown to be a promising solution to improve the\n energy injected to the electrical network. However, the lack of inertia\n in such systems have proven to affect the grid stability, as those\n technologies operate as current controlled sources they not provide grid\n support functionalities. This issue has fostered the implementation of\n new control strategies to enable power plants to provide a coordinated\n action to support some inertia and damping into the system. Synchronous\n controllers have proven to be an excellent option for distributed\n renewable generation, which allows to emulate the inertia of a\n synchronous generators, having a better interaction between the power\n converter and the electrical grid. However, the implementation of such\n control strategies require power converter to be smarter and include\n advanced control algorithms. In this paper, a new control strategy to\n control different distributed generation units to have a coordinated\n action in front of the electrical grid is presented, reducing the cost\n of the power converter by extracting the synchronous control from the\n internal controller and replacing in by a central synchronous\n controller.
